No warm-up
1. Go over dihybrid crosses 2. Review for test 3. Vocabulary STUDY FOR TEST TOMORROW No warm-up- study for quiz
1. Opener- quiz 2. Work session- human traits analysis and human genetic disorders 3. Closing- dihybrid cross practice Warm-up 4: Draw the pedigree for hitchhikers thumb (a recessive trait) in the family described below.
In generation I, Joe who does not have hitchhikers thumb marries Mary who has a hitchhikers thumb. They have 3 children- Mike, Jane, and Jill. Mike and Jill have hitchhiker's thumb. Mike marries Susan (no hitchhikers thumb) they have 2 sons without hitchhikers thumb. Jane marries Bob (hitchhikers thumb) they have a daughter with hitchhikers thumb, one son with hitchhikers thumb and one son without. Jill marries Andy (no hitchhikers thumb) they have two daughters- one with hitchhikers thumb and one without. 1. Opener- correct pedigrees 2. Work session- Dihybrid cross notes 3. Closing- complete pedigrees and dihybrid crosses. HW- study for quiz tomorrow (pedigrees and punnett squares) Warm- up 3: Show the cross between a homozygous dominant individual and a heterozygous individual. What percentage of their offspring will express the recessive trait? Use A's for your letters.
1. Opener: Mendel and his peas https://www.youtube.com/watch?v=Mehz7tCxjSE, correct assignments 2. Work session: Solving pedigrees 3. Pedigree practice HW: Study for quiz Friday (pedigrees and punnett squares) Staple in this order:
